Used primarily as an intermediate in the synthesis of functional dyes and pigments, especially in the production of azo dyes for textiles and inks. It also serves as a building block in the preparation of certain pharmaceuticals and biologically active compounds, where the diamine structure enables coupling reactions. Its methoxy and amine groups make it valuable in organic synthesis for constructing heterocyclic systems. Additionally, it has been explored in the development of electroactive materials and conductive polymers due to its redox-active properties.
